Some old AMD drivers crash when a vbo with stride 1 is used a few times.
I have not found a real solution to this problem. So the solution was to use a vbo with stride 4 (which in theory is less efficient and takes up more memory space).
There is still work needed to be done from multires side to fully
support smooth shading. So can't just always have smooth shading.
Roll back to a proper code in GPU side, the rest will be handled
from CCG side.
The multires sculpt drawing was a not working in smooth mode.
Also hidding was not supported by the wireframe overlay and flat shaded
faces.
Codewise it is cleaner and index buffers are only updated if the
smoothing changes.
The dependency graph now handles updating image users to point to the current
frame, and tags images to be refreshed on the GPU. The image editor user is
still updated outside of the dependency graph.
We still do not support multiple image users using a different current frame
in the same image, same as 2.7. This may require adding a GPU image texture
cache to keep memory usage under control. Things like rendering an animation
while the viewport stays fixed at the current frame works though.
This introduce the wireframe batches. Creating the indices buffer does
not seems to slow down the sculpt in my testing (but it is kind of hard to
test reliably)
This includes a bit of cleanup in gpu_buffers.c.
Needed to fix T61196, supporting clipped back-buffer in the 3D view
which is done outside the draw module.
It was also inconvenient having DRW_shader_* versions of GPU_shader_*
API calls.
- Clipping distances are now supported as a shader configuration
for builtin shaders.
- Add shader config argument when accessing builtin shaders.
- Move GPU_shader_create_from_arrays() from DRW to GPU.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
Was generating INVALID_FRAMEBUFFER here instead of failled texture alloc.
Add safety asserts in gpu_texture.c and clamp minimum size to 1 inside
GPU_offscreen_create.
This is in order to make the API more multithread friendly inside the
draw manager.
GPU_shader_get_uniform will only serve to query the shader interface and
not do any GL call, making it threadsafe.
For now it only print a warning if the uniform was not queried before.
This removes code duplication and put an end to the old "create at request"
batch creation.
Also it uses the same vbo as the uv layer used for shading. Reducing VRAM
usage.
Also fixes the modified uv display in uv edit mode.
